The third one is the answer for this question
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
About 3.8 hours, if asking for a whole number round to 4
Answer:
two equal parts .
Step-by-step explanation:
The bisector is breaking the attribute or the objects into the 2 equal parts that are equivalent. The bisector is applied to the segments with the angles and the curves.
- We can draw the line that divided the into the 2 angle or the two parts the two angle are of equal angle .
- The two angle that are of equal is known as bisector angle .
